ADC3xxxEVM and ADC3xJxxEVM
This document is a user’s guide for the ADC3xxxEVM and ADC3xJxxEVM. The EVMs provide a platform
for evaluating the ADC3xxx and ADC3xJxx. The ADC3xxx is a dual-channel or quad-channel, 12-bit or 14-
bit, serial LVDS interface analog-to-digital converter (ADC). The ADC3xxx comes with sampling speed
grades of 25 MSPS, 50 MSPS, 80 MSPS, and 125 MSPS. The ADC3xJxx is a dual-channel or quad-
channel, 12-bit or 14-bit, JESD204B-compliant interface ADC. The ADC3xJxx comes with sampling speed
grades of 50 MSPS, 80 MSPS, 125 MSPS, and 160 MSPS. This family of converters requires only a
single 1.8-V supply, provides flexible input clock dividers, and provides internal features for improved 1/f
(ADC32xx, ADC34xx) and SFDR performance. Throughout this document, the abbreviations EVM and
ADC3xxxx, and the term
evaluation module
are synonymous with the ADC3xxx EVM and ADC3xJxx EVM,
unless otherwise noted.
